Title: Minor changes in Social for FB integration.

I needed to do some minor changes to use FacebookProcessor from picketlink-social to be used for GateIn integration.
My changes:
1) Have returnURL to be protected to allow accessit from subclasses,
2) Add FB username to FacebookPrincipal and fill it from JSON response
